【０００１】[0001]
この考案は、内輪の内径の異なる一対の転がり軸受の両内輪の内周部に跨がっ て配置され、これら転がり軸受の組立状態を保持する転がり軸受の保持リングに 関する。 The present invention relates to a retaining ring for a rolling bearing which is disposed over the inner peripheral portions of both inner rings of a pair of rolling bearings having different inner diameters and which holds the assembled state of these rolling bearings.
【０００２】[0002]
大型車用のデファレンシャル装置において、一方の軸端にドライブピニオンギ アが形成されたドライブピニオンシャフトに、段突き部を挟んで大径部と小径部 とを設け、これら大径部および小径部をそれぞれ支持する大径部用の転がり軸受 および小径部用の転がり軸受を、ユニット化していわゆるデフユニット軸受装置 を構成したものがある。 In a differential device for large vehicles, a drive pinion shaft having a drive pinion gear formed at one shaft end is provided with a large-diameter portion and a small-diameter portion with a stepped protrusion sandwiched between these large-diameter portion and small-diameter portion. There is one in which a rolling bearing for a large diameter portion and a rolling bearing for a small diameter portion, which are respectively supported, are unitized to form a so-called differential unit bearing device.
【０００３】 通常、転がり軸受は、工場出荷からユーザによって使用されるまでにばらけな いように、環状の保持リングによって、組立状態に保持されている。 上記のデフユニット軸受装置においては、図４に示すように、大径部用の転が り軸受Ｂの内輪Ｂ３に内嵌されて当該転がり軸受Ｂ２の組立状態を保持する環状 の大径側保持部９０ａと、小径部用の転がり軸受Ｃの内輪Ｃ２に内嵌されて当該 転がり軸受Ｃの組立状態を保持する環状の小径側保持部９０ｂとが一体に形成さ れた保持リング９０が用いられている。ドライブピニオンシャフト１には、転が り軸受Ｂによって支持される大径部１ａと転がり軸受Ｃによって支持される小径 部１ｂを有している。Usually, the rolling bearing is held in an assembled state by an annular holding ring so that the rolling bearing does not come loose from the time of shipment from the factory until it is used by a user. In the above-mentioned differential unit bearing device, as shown in FIG. 4, an annular large-diameter side retainer that is fitted in the inner ring B3 of the rolling bearing B for the large diameter portion and holds the assembled state of the rolling bearing B2 A holding ring 90 integrally formed with a portion 90a and an annular small-diameter side holding portion 90b which is fitted into the inner ring C2 of the rolling bearing C for the small diameter portion and holds the assembled state of the rolling bearing C is used. ing. The drive pinion shaft 1 has a large diameter portion 1a supported by a rolling bearing B and a small diameter portion 1b supported by a rolling bearing C.
【０００４】[0004]
ところで、上記の保持リング９０は、ドライブピニトンシャフト１を転がり軸 受Ｂ，Ｃに圧入する際に、当該ドライブピニオンシャフト１の所定部によって当 接されて転がり軸受Ｂ，Ｃから離脱されてしまうことが、デファレンシャル装置 の組立性の点から望ましい。 By the way, when the drive pinionton shaft 1 is press-fitted into the rolling bearings B and C, the retaining ring 90 is contacted by a predetermined portion of the drive pinion shaft 1 and separated from the rolling bearings B and C. Is desirable from the standpoint of assembling the differential device.
【０００５】 ところが、大径側保持部９０ａの取付外径Ｄ（すなわち内輪Ｂ２の内径）が、 小径部用の転がり軸受Ｃの内輪Ｃ２の内径ｄよりも大きいので、当該大径側保持 部９０ａが多少縮径したとしても、小径側の内輪Ｃ２の図において左端部に引っ 掛かり当該内輪Ｃ２内へ移動できない場合があった。したがって、ドライブピニ オンシャフト１の圧入に伴って大径側保持リング９０を転がり軸受Ｂ，Ｃから、 確実に離脱させることができなかった。However, since the mounting outer diameter D of the large-diameter side holding portion 90a (that is, the inner diameter of the inner ring B2) is larger than the inner diameter d of the inner ring C2 of the rolling bearing C for the small-diameter portion, the large-diameter side holding portion 90a. Even if the diameter of the inner ring C2 is slightly reduced, the inner ring C2 on the smaller diameter side may be caught in the left end portion of the drawing and cannot be moved into the inner ring C2. Therefore, the large-diameter side retaining ring 90 could not be reliably separated from the rolling bearings B and C as the drive pinion shaft 1 was press-fitted.
【０００６】 この考案の目的は、上記の技術的課題を解決し、段突き軸の圧入に伴って転が り軸受から確実に離脱できる転がり軸受の保持リングを提供することである。An object of the present invention is to solve the above technical problem and to provide a retaining ring for a rolling bearing which can be reliably separated from the rolling bearing when the stepped shaft is press-fitted.

上記の構成によれば、段突き軸を一対の転がり軸受の内輪内へ圧入する動作に 伴って、段突き軸の所定部が小径側保持体の突き当て部に突き当てられ、小径側 保持体は、圧入方向に移動される。この小径側保持体に引っ張られた複数の弾性 体からなる大径側保持片は、環状の径を縮小するように内径側に変形しながら小 径部用の転がり軸受の内輪内に、容易に導入される。この状態で段突き軸をさら に圧入方向に移動させることによって、保持リングは、一対の転がり軸受から確 実に押し出される。 According to the above configuration, a predetermined portion of the stepped thrust shaft is abutted against the abutting portion of the small diameter side holding body in accordance with the operation of press-fitting the stepped thrust shaft into the inner rings of the pair of rolling bearings, and the small diameter side holding body Are moved in the press-fitting direction. The large-diameter side holding piece made up of a plurality of elastic bodies pulled by the small-diameter side holding body is easily deformed in the inner ring of the rolling bearing for the small diameter part while deforming to the inner diameter side so as to reduce the annular diameter. be introduced. By further moving the stepped shaft in this state in the press-fitting direction, the retaining ring is reliably pushed out from the pair of rolling bearings.
